Postdoctoral Research Assistant in Experimental Petrology

The primary aim of my research is to define the thermodynamic activities of volatiles, such as the halogens and sulphur, in silicate melts. Although they are typically found as minor components in many magmatic and hydrothermal systems they are thought to greatly influence the chemical and physical properties of a melt, the genesis and evolution of magmas and their eruptive processes. In an attempt to understand and model the properties of a melt, the fluids they exsolve and the glasses they form, a detailed understanding of the underlying thermodynamic properties is vital.
